FLOOR COVERING.

Application filed January 3, 1924. Serial No. 684,157.

This invention relates to floor covering, having more particular reference to a cushioning element interposed between the floor and the carpet laid thereon, the invention having for an object the provision of a novel element of this sort characterized by improved cushioning qualities.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claim in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a perspective view showing a portion of the top sheet of my improved cushion element.

Fig. 2 is a vertical sectional view showing the floor covering in place.

Fig. 3 is a fragmentary plan view showing a slightly modified construction of the top sheet.

Fig. 4 is a similar view to Fig. 2 but showing a further modification.

In Fig. 2 of the drawing the reference numeral 10 indicates a floor of any sort, and 11 a carpet of any usual material. According to my invention I provide, for interposition between the carpet and the floor, a novel form of cushioning element, one of whose main features is the cellular structure of one of its sheets. As here shown this cushioning element is of laminated structure and comprises upper and lower sheets 12 and 13 respectively of fibrous material between which is a sheet 14 of fabric material. This fabric material may be conveniently of bur lap, while the fibrous material preferably consists of felt. As here shown the top one of the felt sheets is relatively thick, and in the forming of the said sheet, the top portion thereof is given a cellular structure or form, being depressed into the shallow recesses 16 separated by the intersecting rows of ribs 17 and 18, the recesses being here shown as of square outline. WVhen the carpet is in position it rests on these ribs, and in consequence the resiliency or cushioning effect of the floor covering as a whole is greatly increased, giving to carpets with comparatively short nap the feel under foot of long napped carpets.

In Fig. 3 I have indicated the top sheet.

of the cushioning element as formed, in addition to the top cellular structure, with a like structure impressed on its under surface, the ribs 17 and 18 of this under structure extending at an angle of forty-five degrees with respect to the ribs of the top structure.

In the construction indicated in Fig. 4 I have shown the bottom fabric sheet 13 as also formed on one surface with a cellular structure, the ribs 17 and 18 of which run at an angle of forty-five degrees with respect to the ribs of the top sheet 12 the relation of the cellular structure in the bottom sheet with respect to that of the top sheet being the same as is indicated by the dotted lines in Fig. 3.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as follows:

A floor covering including at least three laminations of filamentous material, the intermediate lamination of which is of relatively coarse mesh of fibrous threads and one at least of the outside laniinations being cellular on its outer surface, and the three laminations being pressed together with fibres on the inner surface of the outer laminations extending through the coarse mesh of the intermediate laminations and joined together to form a union between the several laminations and a substantially homogeneous product.

In testimony whereof I have signature.
